US Congressman George Santos' claim that his mother died in connection with the September 11 attacks is untrue according to reports in the US highlighting immigration paperwork revealed she wasn't in America at the time.
A visa application from his mother Fatima Horta Devolder showed that she was living in Brazil from 1999 until 2003.
The paperwork flies in the face of a claim made on Santos' campaign website.
The visa application was made public by Jennifer Mendelsohn of the Centre for Jewish History.
"George's mother was in her office in the South Tower on September 11, 2001, when the horrific events of that day unfolded," his website read.
"She survived the tragic events on September 11th, but she passed away a few years later when she lost her battle to cancer."
In July, he tweeted that "9/11 claimed my mothers life".
She actually died in 2016.
Santos represents a seat in suburban New York, which was home to many 9/11 victims.

The visa application also disputes other claims made by Santos.
The congressman claimed his mother was born in Belgium, when the paperwork shows she was born in Brazil.
He had also claimed his grandparents were Jewish Holocaust survivors, when the application showed his maternal parents were born in Brazil.
Santos also claimed his mother worked in finance, when the application states her profession as "home aid" and "housekeeper".
What did George Santos lie about?
It has been revealed the New York Republican lied about his resume, education, ethnic background, relationship history, real estate portfolio and charitable activities.
Santos also claimed his mother was a trailblazing financial executive who died as a result of the September 11 attacks.
Her friends described her as a cook and cleaner who died in 2016.
The New York Times today published Santos' resume.
Santos claimed to have doubled revenue for a department at investment bank Goldman Sachs in eight months, from US$300 million to US$600 million.
Goldman Sachs said Santos never worked for them.
The resume also touted degrees from two universities, neither of which he attended.

Despite Santos' disputed claims, he has not been cut off from the Republican caucus in the House of Representatives.
Disgraced representatives are often blocked from having committee assignments, but today Santos was announced as a member of the Small Business Committee and the Science, Space and Technology Committee.
